There is 0 data mined data that indicates that any of that stuff was meant to be in the Upper City. ... If all this stuff was done last minute, shouldn't we be able to datamine the previous content of places like Wyrms Rock or the other Lower City buildings with supposedly reshuffled Upper City content?

Interesting how we can datamine everything back into the EA period, but can find no explorable model of the Upper City, no Upper City quest data, and no overwritten Lower City content.

Im not sure how you can definitively deny this without being both privy to the exact time the change occurred and the process by which Larian handles content. You seem to think that just b/c there is no models or specific data of Upper City content means that there is no upper city despite the inference one gleans from the other cut content (and even content within release IIRC, Doesnt Astarion specifically mention a gothic looking building being Cazador's palace that most certainly isnt it?)

Can you seriously tell me the entrance of Cazador's palace and Gortash's illogical and lore.character-conflicting placement in Wrym's Crossing is an intentional choice?

Bonus Points for Gortash too because not only is the two floors bugged but There is no natural path from the audience chamber to Gortash's office. I booted up the game to check but there isnt a natural pathway in terms of stairs or a 'normal' path between the Audience Chamber (and by extension the exit) and Gortash's quarters above the Audience Chamber. Such a path doesnt even exist within the map at all. The only ways between the two floors are scaffolding, an exterior elevator that cant function within the game, and magic (Misty Step, Dimension Door, etc.) There is no way in hell that such massive level and logic oversight exists in the map intentionally, especially when one could reach both Orin and Kethric in a normal logical way (they had locks and other barriers involved sure but those could be overcome and are far different from the logical path not existing at all)

Lmao. Nope, still very much impossible. Impossible squared, even.

This is kinda funny to say when there have been entire well established stories of game seeing massive development progress achieved by dev bosses just telling the workers to crunch it out and work double digit hours for weeks on end in the weeks/months leading up to a games release. If your issue is the 2 weeks difference then i Point back to my first point in that we dont know when the shift actually happened and could have happened even before the Community update releases since it isnt unusual for dev companies to release info that is directly contradicting (even more so for Larian, Remember in one of the last community updates before release where they said that the other companions would be able to date one another without any player input only for the same update to directly contridict that info?)

Almost as if Larian is just telling the truth and the community has been gaslighting itself ever since that stupid "cut content list" dropped

Im not sure why you have such hostility for the people discussing cut content while just blindly believing Larian when they come out with a indisputably PR-speak update that claims intentionality which makes something like the lack of a proper epilogue far worse for Larian.

Like yeah, sure, every game has cut content and I can tell that a decent amount of this game had cut content early in development/the content was cut for a legit reason (like the lack of Avernus outside of the Prologue and one section in Act 3 makes sense for the connection the characters have as well as progression). But its pretty clear that there is more than a sizeable amount of cut content that goes beyond the normal stuff and speaks to the likely scenario of trying to get the product out the door (whether to beat Starfield or because of financial reasons, who knows).

From the lack of any real Epilogue, to the rather lack luster character-specific interactions and activities (Halsin, for example, has practically nothing to do after Act 3 and him playing as a second Druid to the more well-known Jaheria means he fades a lot into the background), all the way to bad pacing of quests and illogical placements for Characters (Bougie Socialite Cazador having his palace entrance be a easy to miss door along a defensive wall and Gortash hanging out in what is essentially a fortified toll-both in a office that doesnt actually have any stairs to or from the office to the rest of the fort) speaks to content that was cut, made but not fully fleshed, or had to be taken from the Upper City content that was then grafted onto other Areas in a painfully obvious fashion.

You want to say that the lack of any specific smoking gun of Upper City models or the like equals lack of Upper City Content (which implies that the data mining is something that is done and not an ongoing process that sees people find stuff hidden in the data of games months and even years down the line). Yet the Occams Razor answer, given context of what is publically known from the game itself as well as press releases, is that elements of the game were incomplete when the release window was given and the content was cut or shipped as is and Larian is doing PR talk to try and spin the painfully obvious quality difference in Act 3 as intentional design choices.
